Description

JOINTDEDEGAZAGEPOURBOUCHONS JOINTDEDEGAZAGEPOURBOUCHONS
L'invention concerne un joint de dégazage destiné à être positionné dans le fond d'un bouchon, couvercle ou équivalent. Elle se rapporte également au procédé de fabrication dudit joint de dégazage.The invention relates to a degassing gasket intended to be positioned in the bottom of a cap, lid or equivalent. It also relates to the method of manufacturing said degassing gasket.
Certains liquides, lorsqu'ils sont conditionnés dans des récipients fermés, produisent du gaz dont le volume peut conduire à la déformation du récipient. On observe notamment ce phénomène lors du stockage de certains produits alimentaires, tels que boissons à base de jus de fruits, etc.. Ce dégazage reste donc un problème dans la mesure où la déformation du récipient peut avoir un impact négatif sur l'impression que peut avoir le consommateur de la qualité du produit.Some liquids, when packaged in closed containers, produce gas whose volume may lead to the deformation of the container. This phenomenon is particularly observed when storing certain food products, such as fruit juice drinks, etc. This degassing therefore remains a problem insofar as the deformation of the container may have a negative impact on the impression that can have the consumer the quality of the product.
Plusieurs solutions ont été proposées pour résoudre le problème du dégazage, avec pour objectif, d'évacuer le gaz sans pour autant avoir de perte de liquide.Several solutions have been proposed to solve the problem of degassing, with the objective of evacuating the gas without having any loss of liquid.
Le document FR- A- 2 259 026 décrit par exemple un joint de dégazage se présentant sous la forme d'une pastille de polytétrafluoroéthylène, d'épaisseur constante, appliquée dans le fond du bouchon. Pour permettre l'évacuation des gaz, le bouchon est muni d'une ouverture.Document FR-A-2 259 026 for example describes a degassing gasket in the form of a polytetrafluoroethylene pellet, of constant thickness, applied in the bottom of the plug. To allow the evacuation of gases, the cap is provided with an opening.
On retrouve un système similaire dans le document US- A-6 196 409 qui décrit également l'idée de positionner une membrane perméable aux gaz et imperméable aux liquides dans le fond d'un bouchon, lui-même percé d'un orifice d'évacuation.A similar system is found in US-A-6196409 which also discloses the idea of positioning a gas-permeable and liquid-impermeable membrane in the bottom of a plug, itself pierced with an orifice of evacuation.
Dans les deux cas, le produit est en contact avec l'air extérieur, ce qui est incompatible avec une utilisation dans le domaine alimentaire.In both cases, the product is in contact with the outside air, which is incompatible with a use in the food field.
Le document EP-A-O 546 170 décrit un joint d'étanchéité constitué d'une membrane perméable aux gaz et imperméable aux liquides, constitué par l'association de deux couches, respectivement une couche d'un polymère hydrophobe poreux et une couche constituée d'un support textile, l'ensemble étant scellé au niveau de sa périphérie, directement sur le récipient. Là encore, le produit est en contact avec l'air ambiant. Par ailleurs, la fabrication du joint ainsi que sa mise en place sont particulièrement compliquées.EP-A-0 546 170 discloses a seal consisting of a gas-permeable and liquid-impermeable membrane consisting of the combination of two layers, respectively a layer of a porous hydrophobic polymer and a layer consisting of a textile support, the assembly being sealed at its periphery, directly on the container. Again, the product is in contact with the ambient air. Moreover, the manufacture of the seal and its implementation are particularly complicated.
En d'autres termes, le problème que se propose de résoudre l'invention est de développer un joint de dégazage qui ne présente pas les inconvénients ci-avant évoqués, à savoir un joint facile à fabriquer et donc peu coûteux.In other words, the problem to be solved by the invention is to develop a degassing gasket that does not have the disadvantages mentioned above, namely a seal easy to manufacture and therefore inexpensive.
Pour ce faire, le Demandeur a développé un joint de dégazage destiné à être logé directement dans le fond du bouchon, couvercle ou équivalent, sans perçage de ce dernier.To do this, the Applicant has developed a degassing gasket intended to be housed directly in the bottom of the cap, lid or equivalent, without drilling the latter.
Plus précisément, l'invention a pour objet un joint de dégazage destiné à être positionné dans le fond d'un bouchon ou équivalent, qui se caractérise en ce qu'il comprend un support plan muni d'un orifice traversant, ledit support étant recouvert sur la totalité d'au moins une de ses faces, y compris la surface de l'orifice, d'un film laissant passer les gaz et imperméable aux liquides.More specifically, the subject of the invention is a degassing gasket intended to be positioned in the bottom of a plug or equivalent, which is characterized in that it comprises a flat support provided with a through orifice, said support being covered on all of at least one of its faces, including the surface of the orifice, a gas-permeable and liquid-impermeable film.
En d'autres termes, l'invention consiste en une pastille réalisée en un matériau, de préférence d'épaisseur constante, percée d'un orifice recouvert à au moins une de ses extrémités, au moyen d'un film agencé sur la totalité de la surface de la pastille.In other words, the invention consists of a pellet made of a material, preferably of constant thickness, pierced with an orifice covered at at least one of its ends, by means of a film arranged on the whole of the surface of the pellet.
Avantageusement, l'orifice est unique et positionné au centre du joint, ce qui permet une évacuation homogène des gaz.Advantageously, the orifice is unique and positioned at the center of the seal, which allows a homogeneous evacuation of gases.
En pratique, le support se présente sous la forme d'une mousse constituée de polyoléfine avantageusement choisie dans le groupe comprenant le polypropylène ou le polyéthylène et plus généralement, tout matériau compatible avec le contact alimentaire. Ce support peut être d'épaisseur variable, en pratique compris entre 0,1 et 5 mm.In practice, the support is in the form of a polyolefin foam advantageously chosen from the group comprising polypropylene or polyethylene and more generally, any material compatible with the contact food. This support may be of variable thickness, in practice between 0.1 and 5 mm.
Bien entendu, la forme du support sera fonction de la forme du bouchon dans le fond duquel il doit être logé. En pratique, le support est de forme générale circulaire. En ce qui concerne l'orifice, celui-ci peut être de plus ou moins grande taille en fonction de la nature et du volume des gaz à évacuer. Par ailleurs, il peut être centré ou non par rapport à la surface du support et de forme identique ou non.Of course, the shape of the support will be a function of the shape of the plug in the bottom of which it must be housed. In practice, the support is generally circular in shape. As regards the orifice, it may be larger or smaller depending on the nature and volume of the gases to be evacuated. Moreover, it can be centered or not with respect to the surface of the support and of identical shape or not.
Dans un mode de réalisation préféré, l'orifice est de forme identique à celle du support et centré par rapport à la surface dudit support.In a preferred embodiment, the orifice is of identical shape to that of the support and centered with respect to the surface of said support.
En ce qui concerne la membrane perméable aux gaz ou imperméable aux liquides, celle-ci est, comme déjà dit, appliquée sur la totalité d'au moins une face du support et recouvre la lumière ménagée par l'orifice.Regarding the gas permeable membrane or liquid impermeable, it is, as already said, applied to all of at least one side of the support and covers the light formed by the orifice.
Dans un mode de réalisation perfectionné, chacune des deux faces du support est recouverte d'un film perméable aux gaz et imperméable aux liquides. Ce type de joint permet de moduler la vitesse d'évacuation des gaz. En outre, d'un point de vue mise en place dans le bouchon, la présence des deux films permet au fabriquant de livrer les joints en vrac, sans se préoccuper de la question de savoir s'il y a un envers ou un endroit. Dès lors, il n'y a plus de problème pour la mise en place du joint dans le bouchon, puisqu'ils ont une structure uniforme.In an improved embodiment, each of the two faces of the support is covered with a gas-permeable and liquid-impervious film. This type of gasket makes it possible to modulate the gas evacuation speed. In addition, from a point of view put in place in the cap, the presence of the two films allows the manufacturer to deliver the joints in bulk, regardless of whether there is a back or a place. Therefore, there is more problem for the establishment of the seal in the cap, since they have a uniform structure.
Bien entendu, le choix du nombre de films et des matériaux constitutifs et de l'épaisseur du film seront fonction de la vitesse de dégazage souhaitée. Sur la base d'un même film, le dégazage sera plus lent lorsque le joint de dégazage sera muni de deux films, que lorsqu'il sera muni d'un seul film. Bien entendu, la vitesse de dégazage pourra être également modulée en prévoyant, dans le mode de réalisation à deux films, la présence de film de nature ou épaisseur différente.Of course, the choice of the number of films and the constituent materials and the thickness of the film will depend on the desired degassing rate. On the basis of the same film, the degassing will be slower when the degassing gasket will be provided with two films, than when it will be provided with a single film. Of course, the degassing speed may also be modulated by providing, in the two-film embodiment, the presence of film of different nature or thickness.
Pour faciliter l'évacuation des gaz, le film est constitué de fibres de polyéthylène haute densité.To facilitate the evacuation of gases, the film is made of high density polyethylene fibers.
Pour avoir au contraire un dégazage lent, le film est un film de polyéthylène comprenant des charges minérales telles que du talc ou du kaolin.To have a slow degassing on the contrary, the film is a polyethylene film comprising mineral fillers such as talc or kaolin.
Pour faciliter l'évacuation de gaz, le fond du bouchon ou couvercle est rainure.To facilitate the evacuation of gas, the bottom of the cap or lid is grooved.
L'invention concerne donc également un bouchon ou équivalent dans le fond duquel le joint ci-avant décrit est logé, le bouchon se caractérisant en ce que son fond est rainure. Plus généralement, le bouchon à fond rainure peut être utilisé avec n'importe quel type de joint de dégazage.The invention therefore also relates to a plug or equivalent in the bottom of which the seal described above is housed, the plug being characterized in that its bottom is grooved. More generally, the grooved plug can be used with any type of degassing gasket.
L'invention concerne également le procédé de fabrication du joint de dégazage précédemment décrit. Ce procédé comprend les étapes suivantes : - perforation d'orifices au travers d'un support,The invention also relates to the method of manufacturing the degassing gasket described above. This process comprises the following steps: perforation of orifices through a support,
- contre-collage d'un film continu perméable à l'air et imperméable aux liquides sur la totalité de la surface d'au moins une face, avantageusement les deux faces du support, y compris la surface correspondante de l'orifice, découpage des joints individuels.- Adhering a continuous film permeable to air and impervious to liquids over the entire surface of at least one face, preferably both sides of the support, including the corresponding surface of the orifice, cutting individual joints.
Les joints individuels sont en outre découpés dans le support en fonction de la forme du bouchon dans lequel ils sont destinés à être insérés. En pratique, le joint présente un seul orifice positionné en son centre.The individual seals are further cut from the support depending on the shape of the plug into which they are to be inserted. In practice, the seal has a single orifice positioned at its center.
En pratique, le contre-collage est effectué à chaud dans une calandre. L'invention et les avantages qui en découlent ressortiront mieux de l'exemple de réalisation ci-après, à l'appui des figures annexées.In practice, the lamination is carried out hot in a calender. The invention and the advantages which result therefrom will emerge more clearly from the embodiment example below, in support of the appended figures.
La figure 1 est une représentation de face d'un joint de dégazage. La figure 2 est une représentation en coupe selon la ligne A-A' de la figure 1.Figure 1 is a front view of a degassing gasket. FIG. 2 is a representation in section along line A-A 'of FIG.
La figure 3 est le mode de réalisation préféré de l'invention, en coupe, dans lequel le joint de dégazage comprend deux films perméables aux gaz.Figure 3 is the preferred embodiment of the invention, in section, wherein the degassing gasket comprises two gas-permeable films.
La figure 1 est une représentation d'un joint de dégazage rond défini par la référence générale (1). Ce joint se présente sous la forme d'une mousse de polyéthylène (2) et contient en son centre, un orifice circulaire (3). L'orifice est recouvert à une de ses extrémités d'un film perméable aux gaz et imperméable aux liquides (4). Ce film est constitué de fibres de polyéthylène haute densité.Figure 1 is a representation of a round degassing gasket defined by the general reference (1). This seal is in the form of a polyethylene foam (2) and contains in its center, a circular hole (3). The orifice is covered at one end with a gas-permeable and liquid-impermeable film (4). This film is made of high density polyethylene fibers.
Sur la vue en coupe de la figure 2, on retrouve le support (2) d'épaisseur constante, égale à 2 mm, ainsi que l'orifice (3). Sur une des faces du support est appliqué par contre-collage à chaud, le film perméable aux gaz (4).In the sectional view of Figure 2, there is the support (2) of constant thickness, equal to 2 mm, and the orifice (3). On one side of the support is applied by hot gluing, the gas permeable film (4).
Dans le mode de réalisation représenté sur la figure 3, le joint de dégazage (1) présente un film perméable aux gaz et imperméable aux liquides (4, 5) sur chacune de ses faces.In the embodiment shown in FIG. 3, the degassing gasket (1) has a gas-permeable and liquid-impervious film (4, 5) on each of its faces.
L'invention et les avantages qui en découlent ressortent bien de la description qui précède. On note en particulier, la facilité de fabrication et de mise en place du joint, permettant une diminution substantielle des coûts. The invention and the advantages derived therefrom are apparent from the foregoing description. In particular, we note the ease of manufacture and implementation of the seal, allowing a substantial reduction in costs.
